Minute of KAGRA commissioning meeting

Date: 2018/4/3 11AM~12PM
Attendance: Uchiyama, Kokeyama, Yokozawa, Aso, Izumi
- eZuce: Miyakawa, Yamamoto(Kazuhiro), Suzuki, Hirose, Yamamoto, Inoue, Ushiba, Shoda, Kimura

1. Report of work of the last week and plan of work

IFO: Izumi
- Beam from both X and Y end was confirmed at REFL port.
ETMs: Ushiba
- ETMY damping mirror motion has been suppressed to ~1urad in yaw (Miyamoto).
- ETMX has no heat link and is characterized without heat link. Heat link is connected on Thursday.
RT model
- Cable connection is almost done.
- Dolphin should be connected as soon as possible. It can stop all models connected Delphin.
- BS model will be splitted and one of them will be down sampled to 4kHz.
Oplev: Ushiba
- Test mas calibration was done.
- Length oplev is not ready yet.
- Marionette Oplev will be calibrated when door closed.
CAL: Yamamoto, Yokozawa
- RT calibration using IMC as training of calibration will be tested soon.
- Off line calibration using FIR filter won't be used in phase 1.
DAQ

DAQ fix -> Miyakawa, Yamamoto
Selection of full channel -> DGS Yamamoto
Selection of science channel -> Commissioning Izumi
Screens at control room
- Sensitivity.
- PEM.
- Needs laser safety information.
GW alert: online alert in the control room might be prepared. -> Togoshi
Frequency noise can be measured by middle lock. Large intensity noise can be a problem.
